Quasi-zero stiffness damper unit cell structure, damper and application structure of damper
The invention discloses a quasi-zero stiffness damper unit cell structure, a damper and an application structure of the damper, and belongs to the technical field of vibration isolation. Each unit cell structure comprises two supporting plates, and the first ends of the two supporting plates are jointly fixed to the base. An arch-shaped piece and a sliding rod are arranged between the two supporting plates, the middle of the sliding rod is connected with the two supporting plates through a plurality of crossed rod pieces, each crossed rod piece comprises two connecting rods, the first ends of the two connecting rods intersect with each other, and the crossed portions are connected in a pivoted mode through a first rotating shaft. And the second ends of the two connecting rods are pivotally connected with the two supporting plates through second rotating shafts respectively. According to the quasi-zero-stiffness damper unit cell structure, each unit cell structure is composed of the supporting plates on the two sides, the arch-shaped pieces, the sliding rods and the cross rod pieces, the structural piece for connecting the sliding rods and the supporting plates on the two sides through the cross rod pieces provides the negative stiffness characteristic, and the arch-shaped pieces provide the positive stiffness characteristic; in this way, the positive stiffness and the negative stiffness are combined to achieve the quasi-zero stiffness characteristic.
本发明公开了一种准零刚度阻尼器单胞结构及其阻尼器、阻尼器的应用结构，属于隔振技术领域。单胞结构包括两个支撑板，两个支撑板的第一端共同固定在基座上；在两个支撑板之间设置有拱形件和滑动杆，滑动杆的中部通过若干个交叉杆件与两个支撑板连接，每个交叉杆件包括两根连杆，两根连杆的第一端相互交叉且交叉部位通过第一转轴枢转连接，两根连杆的第二端分别与两个支撑板通过第二转轴枢转连接。本发明提供的准零刚度阻尼器单胞结构，每个单胞结构由两侧支撑板、拱形件、滑动杆和交叉杆件组成，通过交叉杆件将滑动杆与两侧支撑板连接的结构件提供负刚度特性，通过拱形件提供正刚度特性，如此将正刚度和负刚度相结合来实现准零刚度特性。
